Seminal vesicles are the structures of the male reproductive system that produce most of the seminal fluid.
Seminal vesicles are a part of the male reproductive system. They are present in a pair and are attached to the vas deference near the bladder.
They are also called seminal glands even though they are made of both glandular tissues and muscular tissues. They produce the seminal fluid which eventually forms the semen when combined with sperms.
The seminal fluid prepared by these vesicles makes up about 80% of the total volume of semen. It contains various components which help the sperms survive and travel through the vagina for fertilization.
Therefore, most of the seminal fluid in the male reproductive system is produced by the seminal vesicles.
